Productive Performance of Thai Indigenous Crossbred Chicken between Pradu Hangdam Sire and Broiler-Layer Dam

Abstract

The objective of this study was to evaluate the productive performance and carcass characteristics of crossbred chickens from Pradu Hangdam sire and broiler-layer dam. Two groups of Pradu Hangdam sires (Pradu Hangdam KKU and Pradu Hangdam Chiangmai) and two groups of dams (PSB*PSL and PSB*CML) were used in this study. A 2 x 2 Factorial in RCBD with two hatches as blocks were designed. The results showed that, there were no interactions between sire and dam in all traits of interest. Body weight at twelve weeks of age of crossbred chickens from Pradu Hangdam KKU sire (1,765 g) and Pradu Hangdam Chiangmai sire (1,709 g) did not different (P>0.05). Moreover ADG, FCR and carcass characteristics of offspring from different sire lines were not significantly different (P>0.05) as well. However, crossbred chickens from Pradu Hangdam KKU sire gave wider breast width than crossbred chickens of Pradu Hangdam Chiangmai sire (6.73 vs. 6.17 cm). Crossbred chickens from two groups of dam lines showed no difference in all traits of interest. Body weight and ADG at first two weeks showed that crossbred chickens from PSB*PSL dam were higher (P<0.05) than that of crossbred chickens from PSB*CML dam. The conclusion of this study is that breast width of crossbred of Pradu Hangdam KKU sire was higher than that of Pradu Hangdam Chiangmai. However, other traits of crossbred of two groups of sire and two groups of dam did not differ.
